   * To implement printing on a platform, the following functions must be
   * defined:
   *
   * int mch_print_init(prt_settings_T *psettings, char_u *jobname, int forceit)
   * Called once.  Code should display printer dialogue (if appropriate) and
   * determine printer font and margin settings.  Reset has_color if the printer
   * doesn't support colors at all.
   * Returns FAIL to abort.
   *
   * int mch_print_begin(prt_settings_T *settings)
   * Called to start the print job.
   * Return FALSE to abort.
   *
   * int mch_print_begin_page(char_u *msg)
   * Called at the start of each page.
   * "msg" indicates the progress of the print job, can be NULL.
   * Return FALSE to abort.
   *
   * int mch_print_end_page()
   * Called at the end of each page.
   * Return FALSE to abort.
   *
   * int mch_print_blank_page()
   * Called to generate a blank page for collated, duplex, multiple copy
   * document.  Return FALSE to abort.
   *
   * void mch_print_end(prt_settings_T *psettings)
   * Called at normal end of print job.
   *
   * void mch_print_cleanup()
   * Called if print job ends normally or is abandoned. Free any memory, close
   * devices and handles.  Also called when mch_print_begin() fails, but not
   * when mch_print_init() fails.
   *
   * void mch_print_set_font(int Bold, int Italic, int Underline);
   * Called whenever the font style changes.
   *
   * void mch_print_set_bg(long_u bgcol);
   * Called to set the background color for the following text. Parameter is an
   * RGB value.
   *
   * void mch_print_set_fg(long_u fgcol);
   * Called to set the foreground color for the following text. Parameter is an
   * RGB value.
   *
   * mch_print_start_line(int margin, int page_line)
   * Sets the current position at the start of line "page_line".
   * If margin is TRUE start in the left margin (for header and line number).
   *
   * int mch_print_text_out(char_u *p, int len);
   * Output one character of text p[len] at the current position.
   * Return TRUE if there is no room for another character in the same line.
   *
   * Note that the generic code has no idea of margins. The machine code should
   * simply make the page look smaller!  The header and the line numbers are
   * printed in the margin.
